This invention relates to new and useful improvements in sky-lights, and more particularly to what will be known as ventilating skylights, especially adapted for useV on garages and similaibuildings. One of the objects of my invention is' the provision of asky-light member which is so mounted that it may be quickly opened to permit the `injurious and poisonous gases, which fre# i quently accumulate, to escape and thus prevent injurious effects upon j persons `entering the building, which has often'occurred, sometimes resulting in death to the persons effected. Y

Another object of the invention is the provision of a device of the above character which includes a movable frame provided with means, whereby to normally retain the frame in a closed position over an opening in the roof of a buildin and furtherprovided with means, where y to quickly move theframe to an open position when released. With the above and other objects in View, the invention consistsin the novel features of construction, the combination and arrangement of parts hereinafter `more fully set forth, pointed out in the claim, and

shown in the accompanying'drawinga in which Figure 1 is a top plan view of proved device, and

Figure 2 is a transverse sectional view, the open position of the movable closure frame being shown by dotted lines.

In the accompanying drawings, theV nu- Vmeral 1 indicates what may be the roof portion of a garage or similar uilding provided with an opening 2. Positioned in the opening 2 for a substantially tight fit is a body my imframe 3, which in the present instance is shown as rectan ular in shape, although other shapes can used and the opening 2 formed accordingly. In order to support the frame 3 in the opening, the frame is formed with laterally projecting flanges 4,

the lower faces of which are formed to con'- form to the surface of the roof, which in the present instance is substantially flat. The upper faces of these flanges 4 are sloped or inclined, as shown, in order to properly shed any water or moisture therefrom and prevent Ythe same from` seeping beneath the anges and in through the opening 2. Y

The upper ed s of the body frame 3 ex- 55 tend an apprecia le distance abovethe'upper faces of the flanges 4 to form a support for the movable closure frame 5. The frame 5 includes a body portion and cross pieces 6, all of which are Vformed with lateral flanges 7 to support the transparent members 8.

lExtending upwardly from the intermediate portion of one of the flanges 4 is a lug 9,

perforated transversely at itsupper end'to receive tliepivot bolt 10 which alsoveXtends through the perforated ears 11 formedlon one side of the vframe 5. From this it -will Vbe apparent thatthe frame 5'is mounted for of the frame 3 as the hinged side of the` frame 5, are lugs 12, each having an' opening therethrough to receive one end of the springs 13. The other end of each of these springs is coiled around the lugs 12'and then extended toward the other side` of the kframe 3 and slidably disposed channel guides 14. It will be apparent from the foregoing, that the springs 13 will be of sufficient weight as to move the frame 5 ytothe open position shown by dotted lines in Figure 2, this opening movement being created through the pressure of the free ends of the springs 13 against the underside of the frame 5, as shown.

In order to limit the opening movement of y Lthe frame 5 a rod 15 is hingedly connected.

to the lower faeeof the frame 5 as shown at 16, while the lower end of the rod extends downwardly through a perforated ear 17 on the frame 3. The rod 15is slidable through the ear 17 and has a nut 18 threaded onto its lower end. Arranged Vbetween the ear 17 and nut 18 and surrounding the rod 15, is a coil spring 19, the tension of which may be readily adjusted by movement of the nut 18 iii order to limit the swinging movement of the frame 5. The nut 18 is retained in vaii- 'ous adjusted positions by means. of a joint of theframe3, as shown` in Ifigure.v The latch face of the catch member is formed with ar notch to receive the edge of the frame 3 in order to hold the catch in a locked poSition. Attached to the catch member is a cord or chain 22, whereby the eateh may be readily released from engagement with they frame 3 and also used for pulling the frame downwardly to a closed position, and moving the catch Q1 into engagement with the frame From the above deseription, taken in connection with the accompanying drawings, it will be apparent that while my improved sky-lightV constructed so that the frame 5 can be normally held in a closed position, it can be readily released so that the springs 123 will move the frame 5 to an open position. In entering a garage for the purpose of Starting the motor of a motor vehicle the cord or chain 22 can be grasped to release the 'atteh 2l for the purpose of opening the closure or trame 5. in order to permit escape of the poisonous gases that often are formed from the running of the motor, thus preventing accidents that usually occur through the accumulation of these gases in a closed garage or other building housing a motor vehicle.

lVhile yI have shown and described the preferred embodiment of my invention7 it will be obvious that various changes and alterations may be carried out without, departing from the spirit of the invention or the scope of the appended claim.

I claim as my invention:

In a device of the class described and in combination, a body frame` a movable frame hinged to one lside of the body frame, .spring members4 attached at one end to the body frame and their other ends loosely engaged with the movable frame Vlioi' normally urging the same away from the body trame, a perforated ear extending inwardly 'from one side of the body frame, a rod having pivotal connection with the movable frame and movable through said car`l a nut on the lower end of the rod, and a coil spring on the rod between the nut and ear to limit movement of the movable frame.
